Is it ok to complete a rudder check with nose wheel steering off, but with the tug still attached to the aircraft?
No. Do not accomplish the rudder travel check until tug is disconnected and D-ring is observed.
If roll spoilers do not deploy or props do not move into discing upon landing, should you increase or relax forward pressure on the control column?
Relax forward pressure.
Forward pressure on the control column after landing creates uplift on the main wheels, which can decrease braking and defeat the WOW signal for Ground Spoiler deployment.
When does Flap Auto Pitch Trim operate?
During flap extension or retraction (15 to 35 or 35 to 15) the AFCS supplies Automatic pitch trim commands to reduce the pitch trim forces felt on the control columns.
